Don't Spam The Shoot Button
In Space Frog Intern, you'll be able to blast away at enemies that are falling in your direction. However, there is a slight difference compared to other space shooters. In most games like this, you can freely move back and forth and shoot at enemies.
In this game, you move automatically so it kind of operates as both an endless runner and classic space shooter at the same time which is interesting. When you fire a shot with your gun, your character swaps direction and so in order to make a quick turn, you'll need to fire away.
This can be quite confusing early on but also adds to the challenging aspect of it. And so because of this, you won't be able to spam the shoot button as much as you would in other games. You still could, but it throws you off-target since you switch directions. So, at least in the beginning, it might be best to avoid spamming the shooting button.
Take Advantage of The Stomp Attack
Unlike most shoot 'em ups, Space Frog Intern allows you to actually utilize a stomping ability to go along with your shooting. This is in some ways will remind you of Exit The Gungeon which features similar combat and familiar-looking arenas.
You might end up using this ground attack more than your gun attacks. enemies will land quite frequently as it's hard to shoot them all in the air since you can't control where you move. You can't just slide back and forth on the screen spamming the shoot button.
Depending on the size of the enemy, you can use regular and high jumps to take care of your foes. Smaller enemies require shorter jumps as you might expect. Jumping too high will lead you to jump right over them and remember, your character never stops moving.
Finding The Rhythm
OK, so this is more of a mentality tip. When playing Space Frog Intern, just keep everything in mind that we talked about. Knowing that firing your weapon switches your direction and never losing sight of that thought can be paramount to your success.
It's so easy to be running in one direction, seeing an enemy fly down, making you shoot it. Then you quickly go the opposite direction and bump into an enemy that sits on the ground, causing you to lose a life. If you can practice having the awareness when playing, then you'll be a master (I know, it can be tricky at first).
Just remember to try to watch both the skies and ground as best you can. Once you shoot a blast into the sky, be ready to jump on and squash any foes on the ground. The game can play with your mind a bit, no doubt. I guess you can say that game is using your head as a game, whether it was intended or not. But it's this aspect that gives Space Frog Intern a nice extra challenge to it that you can appreciate.
